state the octet rule

Exceptions to the Octet Rule - While the octet rule is very useful for describing bonding in a large number of compounds, there are many exceptions to this rule..

Where duplet is formed? A hydrogen atom has only one electron in its valence shell. It needs one more electron to fill its valence shell. The completed shell has the electronic arrangement of the noble gas helium, yet an octet is not completed. However we still get a stable m..

Ampere's swimming rule states that "if a man swims along the wire carrying current such that his face is always towards the magnetic needle with current entering his feet and leaving his head then the North Pole of the magnetic needle is always deflected towards his left hand"...

According to this rule, electron pairing will not take place in orbitals of same energy (same sub-shell) until each orbital is first singly filled with parallel spin. In other words in a set of orbitals having same energy (degenerate orbitals), the electrons distribute themselves to occup..

For the stability of an ionic compound, each cation should be surrounded by maximum number of anions and vice versa. The number of oppositely charged ions surrounding each ion is called its co-ordination number. The larger is the size of the cation the greater is its coordination number. In other..

It states that when more than one orbital of equal energies are available then the electrons will first occupy these orbitals separately with parallel spins. The pairing of electrons will start only after all the orbitals of a given sub level are singly occupied. This is because electron..

. This is a very important rule and is also called the Octet rule. The presence of 8 electrons in the outermost shell makes the atom very stable. Keeping these points in mind let us write the electronic configuration of elemen..

State an explicit rule for the n th term of the recursively defined sequence, a n = 3 a n - 1 , a 1 = 2. Then use mathematical induction to prove the rule...

SO 2 Here all atoms obey the octet rule. Oxygen and sulphur atoms have six electrons in their outermost shells. The Lewis structure of SO 2 is, S is attached to one O atom through a double bond while to the other O atom through a coordinate bond. All atoms have eig..

The state of equilibrium in any system depends upon factors present in the system, such as temperature, pressure and concentration of various species. These factors are called reaction variables or parameters. A change in any one of the parameters may affect the position of the equi..
